✦ Synopsis


In this paper a new explicit Numerov-type method is introduced. The construction is based on a modification of a sixth-order explicit Numerov-type method recently developed by Tsitouras [Ch. Tsitouras, Explicit Numerov type methods with reduced number of stages, Comput. Math. Appl. 45 (2003) 37-42]. Two free parameters are added in order to nullify the phase-lag and the amplification. The method is useful only when a good estimate of the frequency of the problem is known in advance. The parameters depend on the product of the estimated frequency and the stepsize. Numerical results obtained for well-known test problems show the efficiency of the new method.

This paper deals with the construction of explicit bounds for solutions of second order linear differential equations of the type [p(x)y ( The construction is based on the study of the evolution of two complementary functionals involving y(x) in the sequence of zeroes of y(x) and y (x). Based on th
